I don't know if its the particular asteroid but an asteroid will hit the Earth in a future date and contaminate the seas. It will definitely happen. They know it. That is why they built underground cities to escape the wrath of the lamb when the time comes.So what you trying to say is if we take the bible literal then the water on earth should be contaminated by something 3 millions miles away and I can expect a whole bunch of people to die soon? What's the narrative if nothing happens?
